AWS Certified Data Engineer Associate DEA-C01 Practice Question

Your company stores sensitive PII in an Amazon Redshift RA3 cluster. Security mandates that all data at rest must be encrypted using keys that the security team can audit and rotate within AWS, without operating any hardware security modules. What is the MOST operationally efficient way to meet this requirement?

  • Create an AWS CloudHSM cluster and store the Redshift cluster key there.

  • Configure the cluster to use server-side encryption with customer-provided keys (SSE-C) for its managed storage.

  • Encrypt data client-side before loading, then disable Amazon Redshift encryption to avoid double encryption.

  • Enable cluster encryption with an AWS KMS customer managed key when creating or modifying the cluster.
